The catalytic region of an enzyme is the place where substrate molecules bind and undergo a chemical reaction.
the substrate bonds to the enzyme at the active site
Inter-species gene transfer.
It depends on the species. Most seals are active at night (nocturnal) but there are some that have a tendency to be diurnal.
No species of cat hibernate. They are active year round.
It depends on the species. Some are more active during the day while others are more active at night.
active site
A substrate molecule needs to interact with the enzyme's active center (known as "active site") for the enzyme mediated catalytic conversion of substrate into product. Some times, this could or may bind to a second site of an enzyme named, "allosteric site" that would not form the product.
Many species of dolphins are nocturnal, meaning they are active at night. Those nocturnal species feed at night. Other species sleep or rest during the nighttime hours.
Most species are active at night and sleep during the day.
This largely depends on the species. For the Domestic Cat species, they are more crepuscular than nocturnal. This means they are most active during low-light hours such as at dawn and twilight, due to their prey being most active at this time.
